Piotr Drabik is described as a gifted scientist, a 34-year-old Pole temporarily working in Canada...On September 1, Drabik was supposed to fly to Salt Lake City, switch planes and travel to Hawaii. Authorities believe he landed here [Salt Lake City] from Edmonton, Alberta, but then the trail turns cold...the University of Alberta expected him back within two weeks. Authorities were told of his disappearance September 26..."The airport was apparently the last known place that he was"... Star-Bulletin
